Finding interesting music can be a tedious task in the area, but since my last stay the situation has definitely improved. Below you find links to some labels, collectives and producers in the area. A good overview(though the links are kinda outdated) can be found kongkretebass.com. The platform was founded by Hong Kong based producer DJ Wash, who also hosts the Kongkast, a podcast, which is relaesed twice a month. If you want to see him live, he is currently touring Germany. - Event recommendation in Dresden
Another forward thinking label is Dubtemple Records, based in Brisbane, Australia. Their releases a free for download from the link above. Two of them immediately caught my attention: Blood Dunza and Bunda. Also check the Lee Scratch Perry Beat Tape - compilation.
In Singapore an audiovisual collective called Syndicate SG is filling the void. Check out the amazing sound of Jonathan Nah aka KIAT(you can buy his releases on Qilin) Further have a listen to other artists of the collective on their soundcloud page.
Thailand seems to be a little behind on the heavy bass music but If you are into Disco, definitely check Jaree Thanapuras, Grammaphon Children.

So far so good; lot´s of links, i know.
Have a listen, support the artists and enjoy.
